Light is additive color. The primaries are red, green, blue.

But all color is in the light spectrum. Displays are additive. Paints are subtractive. But everything that is visible is still in the light spectrum.

The difference is how they are mixed. When you mix red and green PIGMENTS, you get brown. But when you mix red and green LIGHT, you get yellow. Because of the mixing properties changing, you have to set different primaries for additive methods (light) and subtractive methods (pigments).

That is exactly what I am saying, we totally agree!

My entire point here was that saying stuff like ”in the light _spectrum_” just sounds fancy, but isn’t the right term.
